Abstract (en)

[origin: EP3065290A1] To provide a motor control device that can determine occurrence of abnormality in a gate buffer. [Solution] A motor control device 1 configured to control a motor, including a gate driving circuit part 30 configured to drive the inverter part, a PWM control part 60 configured to generate a PWM signal applied to the gate driving circuit part 30, gate buffers 12, 22 disposed between the gate driving circuit part 30 and the PWM control part 60, and a device control part 50 configured to apply a test signal to the gate buffers 12, 22 to determine abnormality of the gate buffers 12, 22, the device control part 50 includes a comparative diagnosis part 80 configured to branch and input a switch control signal for conducting or blocking the PWM signal to the gate buffers 12, 22, and a pulse diagnosis part 70 configured to output the test signal to the gate buffer and to determine the abnormality of the gate buffers 12, 22 based on a state of the switch control signal and a state of a signal output from the gate buffers 12, 22.
